A hippopotamus can stay under water for 15 minutes. A sea cow can stay under water y minutes.This is 11 minutes longer than one-

Answer:

<em>The sea cow can stay under water for 16 minutes.</em>

Step-by-step explanation:

A hippopotamus can stay under water for 15 minutes.

A sea cow can stay under water $y$ minutes and this is 11 minutes longer than one-third the time a hippopotamus can.

So, "11 minutes longer than one-third the time a hippopotamus can" means: $[\frac{1}{3}(15)+11] minutes$

Thus, the equation will be: $y= \frac{1}{3}(15)+11$

Now, solving the above equation, we will get.........

$y= \frac{1}{3}(15)+11 \\ \\ y=5+11= 16$

So, the sea cow can stay under water for 16 minutes.
